With politics you never get straight answers. you always get political answers. They answer a question with another question. You see it all the time.
What I would guess is happening in Germany, with the fake news, is a bit like the German government wanting the German public to think that this is what happens if you quit the EU. Make it look much worse in the UK than it really is. Just so happens people from the UK are reading these reports too and know it is not actually happening. Might be one reason why it is happening. To scare anybody who might have any thoughts about Germany leaving the EU.
